Just a few days ago, the Earth witnessed the Geminids meteor shower where the Earth annually passes by the debris left behind by the asteroid 3200 Phaethon. But what we look at as bright, glowing lights across the sky are actually small space rocks or meteors that could just as easily get pulled by the Earth and crash onto it. And this is not just a hypothetical possibility, this happens a lot around the planet. Just seven years ago, on November 13, 2015, a piece of a gigantic asteroid fell near the town of Kamargaon in Assam, India. While it did not cause any major destruction owing to the remote region, the meteorite, which weighed 12 kilograms, could have easily taken many lives. So, what caused this asteroid shard to hit the Earth and why has the Kamargaon meteorite become important for us? Find out.

According to a study published in the Journal of Geophysical Research-Planets, this broken asteroid has conveyed a very important piece of evidence to us that points us towards the origin of life itself. The research is conducted by a team at the Indian Institute of Technology (IIT) Kharagpur who claim that the composition and structure of the Kamargaon meteorite can reveal important information about the volatile gasses that help create and sustain life.

The study theorizes that it belongs to the asteroid belt present between Mars and Jupiter. The region is filled with asteroids that revolve around the Sun in their independent orbits. After the parent asteroid, a 6.4-kilometers wide space rock, collided with another, this piece broke off and began moving towards our planet along with some smaller meteorites.

The researchers have found a systemic type of hole on the asteroid called a vesicle. These vesicles are formed when
